terasse,

citizen jof the UnitedStates, residing at' Columbia, in the county of Richland and State of South Carolina, havev invented new and useful Improvements vin Locomotive Driving fand'lruck Boxes, of which the following isaspeciicat-ion.

Thls invention, relates to improvements in adjusters' for ldcomotive drive'boxes.

At present, when fside -play exists, it is comotive, and-attach faeiplates, to the driving box.andreplace. vThe present invention -obviates ,the Vnecessity lof doing, and is intended -.'tore medy side play-\ in'en.

gine drive lwheels, andit is equallyapplica.

ble to engine truckwheels.

'ith z lgnliabove, and other `objects in `view, whichlwill appear as the description progresses,j 'the,l Ainvention resides in the novel .-{construction and combination .of parts f'hereii'aftef r described 'and claimed;l i

In the aconpahyng drawings, Figura is a frontlelevation of the device. Fig. 2*

is a top jpl'an view 'of the same. Fig'. 3 is a detail view of the liner.` 4Figl a topf,

In the' drawings the numeral 1 designates the usual .-box. rThis box isada'pted tov be mounted "upon an axle to take up Wear be tween-the boxes and the pedestals.

ThenumeralQ designates the liner whichtakesl all the Wear olf .-of'the box. .This liner 2 comprises -a faceplate 3,' the latter' having its .edges beveled yas* at 4 andinclined downwardly and toward the center of the -box 1. The liner 2 is provided with a central opening 5,'the walls of which be-` ing adapted to straddle the axle of the drive Wheels -to prevent lateral movement .and also toprevent thewheels lfrom contacting with the' sides of thebox l. The outer face o f the box is provided with bev.

eled recesses 6, the same being inclined downwardly'or toward thecenter fof the' box so as to provide for the snug reception ofthe liner 2. Bya construction as above described, it will be understood that the i weight of the liner is suficient to cause the y specmcaaon of Letters Patent. 'Application iledseptember 16, 1910.

formed by the box and valso that the thumping of. the wheels when passing over the :joints of the rails will tend to force the wedge shaped liner' tightly within the beveled'recesses'. 'The liner 2 'may, if desired,

be providedwith an extension?, the same being adapted to serve vas a' hand hole when lit is desired to vremove the liner-'from the 4 of the-drawingsthe device. is

It s evident that more or less slight 'changes might be made in theform and arrangement 'of the several parts described without departing from, .the spirit and scopeofth'e inventionl and I do not wish to limit myself to the exact structure herein 'set forth, but-:f-l i I-Iavingjthus fully describedv the inveni.

tion, what'l'claim'as ne'wis:-' '1.The combination with a box having its' outer v'face formed witha depression, the' sidewalls of which -converge downwardly and are undercut?, of a liner comprising a .plate'having .its top, bottom and side edges of equal thlckness, the rear surface of the plate being .wholly plain to slidably engage 'and bear throughout on the bottom wall of the depression or recess in the box face, the side yedges' of the liner converging downwardly .and being beveled'to coperate with the side walls of the box face recess, said box face recess4 opening lwholly through the vertical extent 0f the box 4face whereby,

through their wedge formation.` 2. In a device of the classdescribed, .the

combination with a box having its outer face formed with a depression, the side. walls-of which converge downwardly and through the equal thickness of the top, side "the side walls of the liner and recess are uniformly undercut from top to bottom,l

'of a liner comprising a plate having its rear surface Wholly plain to slidably engage and 'bear throughout on the bottom Wall of said depression in the box face, the liner having edges `converging downwardly to fit against the side edges of said depression, said .edges being uniformly beveled to oooperate with the undercut side edges of the g 1,014,5so

depression to-clamp the liner tight against the bottom of said depression at all points. 10
